ABSTRACT:
A method of manufacturing a multi-layered liquid crystal for a liquid crystal display device in which an electric-field effect type liquid crystal layer is placed between opposing upper and lower electrodes and a plurality of insulating layers are alternately stacked with the liquid crystal layer, includes the steps of forming a lower electrode on a substrate, alternately stacking an insulating layer and a source material layer having a selective dissolving characteristic for forming cavities for a liquid crystal layer, and performing a selective dissolution and liquid crystal injection through well-shaped holes. The method does not need an additional step of forming columns for supporting the liquid crystal layer, thereby achieving a cost reduction. The manufactured product has a much higher light dispersion effect.
